SPECIFICATION forming part of Letters Patent No. 386,431, dated July 17, 1888.

Application filed February 15,

To all whom, it ntay concern/.-

Be it known that l, CHARLES W. HULLINGS, of Burlington, in the county of Burlingtor and State of New Jersey, have invented a new and useful Improvement in Locomotive Fire Boxes, of which the following is a full, clear, and exact description.

This invention relates particularly to an improvement in the fire-boxes of locomotives in which an arched hollow baftler-plate extends from the top of the furnace-opening, in lieu of a door, inward and downward over the grate, so as to prevent the cold air entering at the opening from striking the crownsheet, and thus to consume the smoke and cinders in the furnace, and is supplied with water from the water-tank, so as to guard against burning ou t.

The objects of my invention are to secure a circulation of water through the hollow baffler-plate, so as to effectually prevent its bu rning out, and to facilitate its removal for repairs or renewal.

The invention consists of certain novel featuresofconstruction and combinations ofparts, hereinafter fully described, and distinctly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Fignrelis a side (partly sectional) elevation of apart of alocomotive to which my improvement has been applied. Fig. 2 is an enlarged rear end elevation of the furnace and boiler of same. Fig. 3 is a plan view of the rear part of the boiler and furnace. Fig. 4 is a sectional side elevation of the same on the line as m, Fig. 2.

A designates the furnace; B, the furnaceopening; 0, the boiler; D, the grate; E, the furnace-deflector; F, one of the two boiler feed-pumps; G, one of the two injectors, and H H the two supply-pipes leading from the water-tanks of a locomotive, all of which parts may be of the ordinary description shown.

From the top of the furnace-opening vB a transversely arched hollow baffler plate, I, constructed, by preference, of copper, is arranged to project inward and downward to near the normal level of the fuel on the grate D, for the well-known purpose of deflecting the air entering the opening B upon the fire Serial No. 264,107. (No model.)

and consuming the gas and sparks produced thereby.

The outer end of the hollow bailler-plale I is formed with a, hollow upward and laterallyprojecting flange, 1, the closed chamber of which forms an extension of that in the baffler-platc,and which is arranged to rest against the outside of the furnace-wall A, around the top of the opening B therein.

To opposite sides of the hollow flange are rigidly attached short tubes J J, communieating with the interior thereof, and adapted for connection, by unions J with short bent tubes K K, respectively fixed to the furnacewall A and communicating with the boiler, so that the baftler-plate is thereby both put in connection with the boiler and removably supported in position.

The fixed tubes K K are each provided with a cock, K", so that they can be readily closed previous to detaching the baffler-plate.

From the top of the hollow flange l, on

either side, lead other short tubes, L L, also adapted for detachable connection, by unions L, with the ends of pipes M M, which are carried laterally and oppositely along the outside of the wall A, and forward on opposite sides of the boiler to a connection with the pipes N N, which discharge, as usual, from the two injectors G into the boiler O at the forward part thereof.

The ends of thepipes M M adjacent to the unions L are provided with cocks M, for closing them previous to detaching the bai'flerplate.

Pipes 0 0, provided with cocks 0 are also run from the pipes M M to the feed-pipes P, having cocks 1, leading from the pumps F into the boiler in the ordinary manner, the pipes M M having long-handled cocks M adjacent to their connections with the discharge feedpipes N N, and the pipes N N also having long'handled cocks N between said connec tions and their boiler-connections.

The injectors and pumps are connected, as usual, with the water-supply pipes H H by valved pipes Q, Q and R B, respectively, and a discharge-pipe, S, is arranged to lead from the bottom of the hollow flange 011 the bafflerplate out upon the ash-pan, for emptying the baftler-plate when the same is to be detached.

\Vith the arrangement described, when the boiler is to be fed by the injectors G, by elosing the cocks N and opening the cooks M the fiuid drawn from the water-tank through the pipes H H and Q Q will be discharged through the pipes N N and M M and tubes L L into the baffler-plate, and thence through the tubes J J and K K into the boiler, so that the desired circulation through the bafiler-plate will be obtained.

When the boiler is to be fed by the pumps F, by closing the cocks and opening the cooks Q, the water drawn from the supplypipes H H and R R will be pumped through the pipes O O and M M and tubes L L into the battlerplate, and thence, as before, into the boiler, so that in this way also a circulation of water through the baltler-plate may be obtained.

By closing the cooks M and O and opening the cooks N and P the injector and pump may be caused to feed directly into the forward part of the boiler, when so desired.

All the bat'fler-plate connections, feed pipes, and valves being located outside the boiler, the baffler-plate may be readily detached and replaced without the necessity of putting out the fire.

By thus causing the Water to circulate through the battler-plate it may with perfect safety be brought so close to the fire as to de fleet all the air thereupon, and thus entirely consume all smoke and cinders.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

, 1. The combination, with the locomotiveboiler and fire-box provided with afuel-opeuing, of the hollow batfier extending through the upper part of the fuel-opening and detaehably connected at its outer exposed end with the boiler, whereby it may be readily removed without drawing the fire or emptying the boiler, substantially as set forth.

2. In a locomotive-engine,the combination, with the firebox having a fuel-opening, B, and the boiler, of the arched hollow bafiler extending through the upper end of the fuelopening into the fire-box and detachably connected at its-outer exposed end to the boiler by valved connections, and valved connections between the water-supply pipes and the outer exposed end of said bafller, whereby the valves in said connections may be closed and the baffler removed without interfering with or drawing the fire or emptying the boiler, sub- Stantially as set forth.

3. The combination,with the boiler, the firebox having a fuel-opening, B, the Water-supply, injeetor,and feed-water pipes H H, N N,

and P, and the valved pipes Q Q,of the hollow bai'fler I, extending through the fuel-opening B, valved exterior attaching-connections J J between the baffler and the boiler,valved pipes M M, leading from pipes N N to the baftler, and valved pipes O 0, leading from pipes M M to feed-pipe P, substantially as set forth.
